As technology advances, integrated circuits (ICs) are adapted into ever smaller packages and incorporated into many different kinds of devices. In many cases, so-called Internet of Things (IoT) devices may communicate using integrated wireless circuits. Given the small size of the circuitry involved, many potential sources of interference may be present during wireless communications. For example, when transmitting radio frequency (RF) signals via an associated power amplifier, high currents can cause ground bounce, which can impact duty cycle and thereby even-order harmonic emissions, spurs due to power supply rejection and so forth, and in certain cases adversely impact circuitry of the wireless transmitter itself due to stability issues. Current solutions include providing extensive off-chip filtering circuitry, which comes at an expense of real estate, power and cost consumptions, to meet performance requirements, including harmonic and spurious emissions. And such solutions do not address adverse impacts on power amplifier stability due to inherent feedback through different ground domains itself.
